Cyclin dependent kinases (cdk) are proteins that work with cyclin regulatory proteins. the cyclins are associated with different checkpoints of the cell cycle. different phases of the cell cycle experience activation and/or deactivation of specific cyclin-cdk complexes. cyclinb-cdk1 activity is specific to the g2/m checkpoint. referring to the graph, what is the relationship between the concentration of cyclin b and cdk1 activity?

Cyclin dependent kinase 1 or CDK 1 is a catalytic protein whose action is regulated by cyclin B.

Explanation:

CyclinB-CDK 1 complex is also termed as maturation promoting factor that helps in the entry of the cell into the M phase.The concentration of Cyclin B -CDK1 rises by various process such as dephosphorylation and falls by the degradation of cyclin B.

       The cyclinB-CDK 1 is inactivated by phosphorylation of at tyr 15 residue.cyclinB-CDK1 interacts with various proteins such as survivin,which is essential for spindle formation that in turn regulate the cell viability.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
